<p>The present invention provides one-component silicone compositions, particularly useful as sealants, having low modulus and high elongation, as well as good resistance to high tempertures and humidity, and methods for preparing these sealants. In particular, the present invention provides compositions including a chain-extended curable polyorganosiloxane, a high molecular weight silicone gum and a cure system. The compositions may be used, for example, in sealing the stitching of automotive airbags.</p> |
